    Abstract: Improved area decontamination products and methods of use thereof are provided which include reactive nanoparticles (e.g., metal oxides, hydroxides and mixtures thereof) with one or more biocides and a liquid carrier for the nanoparticles and biocide(s). The products may be formulated for area decontamination as sprays, fogs, aerosols, pastes, gels, wipes or foams, and the presence of reactive nanoparticles enhances the neutralization of undesirable chemical or biological compounds or agents. The nanoparticles may be from the group consisting of the alkali metal, alkaline earth metal, transition metal, actinide and lanthanide oxides and hydroxides and mixtures thereof. In preferred forms, nanocrystalline oxides and hydroxides of Al, Ca, Ce, Mg, Sr, Sn, Ti and Zn are employed having single crystallite sizes of up to about 20 nm and surface areas of at least about 15 m2/g.

  • Patent number: 6824602
    Abstract: An improved block paving sand comprising kiln dried sand mixed with a water-soluble polymer. The block paving sand is filled into gaps between blocks and then water is applied thereto. Upon contact with the water, the polymer coats the sand and then sets hard, thereby stabilising the block paving.

  • Patent number: 6821631
    Abstract: A method of treating substrates, such as wood, including the steps of applying an alkali silicate solution to one or more substrates and applying an alkali borate solution with boric oxide (B2O3) content to the substrates. Substrates that have been treated using the present method include a borate-silicate polymer within the substrate. When the present substrates are wood, wood products, or green lumber, they may be used to build structures.

  • Patent number: 6794318
    Abstract: A use-dependent indicator system for detecting the exhaustion of an active chemical within an absorbent article is provided. The indicator system includes at least one dye component and a polymer mixture. The dye component(s) can be non-reactive and/or reactive dyes. The polymer mixture can contain a polymer, such as a latex adhesive, to facilitate control over the dissolution rate of the dye component(s). By controlling the dissolution rate of the dye component(s), an indicator system of the present invention can impart a change in color to signal the exhaustion of an active chemical incorporated within the absorbent article, such as an anti-microbial agent.
